they enjoy doing harmless pranks on random people (especially to dai) and their shape-shifting ability lets them change into all sorts of different things, ranging from everyday furniture/objects to humans and animals.they also wear human clothing but none of them really fit aki because they are so lanky.. ( also haven't designed it yet, so that's why i didn't draw it here oops;; )

aki almost always has mist/fog/clouds around them, which expand to cover their entire body when they want to transform into different things (such as their human form and other random objects and animals).

(also aki, at least in their demon form, don't really have genitalia but i just felt the need to cover it up for some reason lmao--)
